En mars 2007, le Conseil européen a annoncé qu’à l’horizon 2020, une proportion minimale de 10 % de biocarburants devrait être incorporée dans les carburants utilisés pour le transport routier. Les pouvoirs publics communautaires mettent en avant trois facteurs principaux pour...

A l'aide d'un modèle régional d'offre optimisant le revenu agricole des exploitations sous un ensemble de contraintes et simulant parallèlement les évolutions des structures agricoles sur la période 2002-2012, les impacts du compromis de Luxembourg sur les revenus et sur les structures...

"Sugar is one of the most highly protected agricultural commodities worldwide. This protection depresses trade opportunities and the prices received by exporters without preferential market access. For this reason, dialogues about sugar policy are often polarized and short sound bites caustic....

The paper provides an analysis of the impacts of the biofuel policy on the French arable crop sub-sector. The model used is a biofuel supply model composed of an agricultural module and an industrial biofuel processing module. The agricultural supply model is an aggregation of 1094 farm models,...

This paper addresses the issue of designing policies for habitat conservation on agricultural land. The case under study requires a non-aggregated spatial distribution of the fields to be enrolled in an agri-environmental programme. A spatially explicit mathematical programming farm-based model,...

A mathematical programming model is developed and associated to a spatial pattern index (Ripley L-function) to analyse the optimal reserve design and implementation for the Little Bustard conservation in Plaine de Niort. The model structure corresponds to three spatial levels, fields, farm and...
